An organism's home is called its habitat and its conditions are called the environment.
Physical environment includes conditions such as the temperature and the amount of
All organisms have certain features and characteristics that mean it can successfully live
in its habitat. These are known as adaptations and we say the organism is adapted to its
habitat. Depending on the different habitats, organisms need different adaptations.
Polar bears live in the Arctic, which is cold. Some of the polar bear's adaptations to
living in this environment include:
black skin to absorb heat well
white appearance to camouflage it against the snow and ice
thick layers of fat and fur for insulation
wide feet with hair on their soles to avoid slipping
hollow hairs also for insulation
greasy, waterproof fur
Camels live in deserts, which are hot and dry during the day but cold at night. Some of
the camel's adaptations to living in this environment include:
they can go for a long time without water (but they don't store water in their
slitlike nostrils and two rows of eyelashes to help keep the sand out
wide, flat feet to help them walk on the sand
thick fur to keep the sun off their skin
Many habitats can change and this means that the organism not only has to be adapted
to one environment but also when it changes. For example, during the day the
environment may be different compared to at night. Or regarding the sea, whether it is
high or low tide. There are also longer term changes such as seasonal changes like
from summer through to winter, long days to short and lots of vegetation to bare trees.
Limpets' behaviour changes according to its habitat. When the tide is in, the limpets
crawl around the rocks scraping off seaweed, whereas when the tide is out, the limpets
clamp themselves to the rocks so that predators can't get to them.
